I totally misunderstood the context around this play...
I had originally thought Tom was injured off a Manly attacking kick (which, in that situation, Bronx should definitely be able to grab him in the air).
But catching a defensive kick, regardless of whether it has bounced or not, the player should have the refs protection until he has hit the ground. Its pretty bloody unlikely the rule will be exploited for attacking gain since the other team is deciding where the ball is kicked to, but these players need to be protected when they are so exposed to cheap shots like the one in this game.
As for Brisbanes article, it might have been legal, but calling it a "great play" when it might have ended the kids season is a dick move...
